May be before trying any of solutions you should try to rm ~/.dropbox*. check the right name with nautilus, I don't remember exactly and on windows machine.

What error message do you get when you try to run ~/.dropbox-dist/dropboxd? You should edit your question to tell us this, and also to tell us what you mean by "Runnung Ubuntu on Windows..." Do you have a Wubi system (where you installed Ubuntu while running Windows, then rebooted to get into Ubuntu)? Are you using a virtual machine?

One additional note. When I followed these instructions and then when I start dropbox it says "Dropbox is running from an unsupported location" then it asks me to go to their install page. I hit cancel on that page and then it proceeded to set things up correctly. it did make me a little nervous but it seems to be working.

Seems like proper support for Ubuntu 12.10 has now been added (8th of march 2013?) judging by the existence of this folder: linux.dropbox.com/ubuntu/dists/quantal -- so Achu, you may want to update your answer again.

In case you are using Lubuntu 13.10, it works the same way except that in the last step you run: sudo apt-get update && sudo apt-get install dropbox

This doesn't work on 12.10 (quantal) because dropbox hasn't put a quantal package in its repository. You can see that by manually looking at the repo (http://linux.dropbox.com/ubuntu/dists/) and see that quantal isn't there.

I solved this by using precise in my source file instead of quantal. Technically, I'm using a version of dropbox that's not meant for my system, but I'm assuming the differences are small (it's only 6 months). So far, no problems on two different machines. YMMV.

Note: this is valid as of the time I'm typing this. They may add quantal support in the future.

Download the latest dropbox .deb file from the official site : https://www.dropbox.com/install?os=lnx and run it. When it show the welcome screen, follow it carefully. Just now I installed it on my machine without any issues.

Don't want to seem ungrateful... After re-installing WUBI, i tried again and it worked! It said that Nautilus had to be restarted but nothing ever happened. Clicked next and then it went fine.

Didn't work for me. I get the following error: The following packages have unmet dependencies: nautilus-dropbox : Depends: dropbox but it is not going to be installed E: Unable to correct problems, you have held broken packages.

Hi @Seanny123. Do you use Ubuntu 14.10 ? I can check that tonight...

14.04. Ended up installing via the command line, which seemed to work fine, so don't worry about checking it. I think I just had a weird setup.

Checked it out. The version on DB's site is 1.6.2, but in Ubuntu's repository, it's 1.6.1-1. Still a very simple an nice way. Voted up.
